e Application filed September 2, 1922. Serial No. 585,989.

To all whom t may concern:

Be it known that I, CHARLES H. LANGO, a citizen of the United States ofAmerica, residing at Detroit, Wayne County, Michigan, have invented newand useful Rebound Absorbers, of which the following is a specication.

vices.

This invention has utility when incorporated in connection withresilient load carrying supports as in motor vehicles for absorbingrebound.

Referring to the drawings: i

Fig. 1 is a fragmentary perspective View of a motor vehicle of the Fordtype having incorporated therewith an embodiment ofthe invention of thisdisclosure; Y

Fig. 2 is a section on the line II-IL Fig. 1, on an enlarged scale; i

Fig. 3 is a fragmentary side elevation, of one of the devices as mountedon the rear axle; and

Fig. 4 is a perspective view of a Saddle as a portion of the said linkconnection between the axle and spring.

The motor vehicle in connection with which an embodiment of theinvention is shown as completely equipped may be provided with four ofthese rebound absorbing devices. As herein shown this motor vehicle isshown as being provided with a front axle 1 having upstanding from theendl thereof,

a pivot pin bracket or bearing 2 from which extends a link 3 topivotally engage semielliptic spring 4.' This vehicle is also shown asprovided with a rear axle 5 which has an upstanding pivot pin carryingbracket 6 from which extends a link 7 for pivotal connection with rearcamel-back spring 8. These springs 4 and 8 together mount the load 9 asa frame or chassis of the motor vehicle.

Without any disturbance of the motor vehicle as to assembling structure,there is mounted a device of this disclosure. This device is shown ascomprising a U-bolt main frame portion. These U-bolts are shown ashaving main or central bend providing portions 10 from which extendoutwardly and upwardly are portions 11 to terminate in parallelupstanding leg portions 12. The free ends of these leg portions 12 havethreaded portions 13.

Upon each leg 12 of the U-bolt 10, 11, 12,

This invention relates to resilient link de-` there is disposedy abracket member having an outwardly extending portion 14 provided with aneye 15. Each of these outward extending portions has anv inwardlylupwardly extending plortion 16 to complete an L-bracket 14, 16. heseupstanding portions 16 are each provided, near the upper end thereof,with an eyey 17, through which may extends` a'bearing pin or rocker pin18 having upon the outer sides of the upstanding portions 16 of theL-braeket 14, 16, head portions 19. The rocker pin`18'has bearingconnections with the eyes 17 so there may be rocker movement of the pin18 as to the portions 16 of the L-brackets 14, 16. Furthermore, the eyes15 of these L-brackets 14, 16, are quite loosely connected or movable asto the upstanding leg portions 12 ofthe U-bolt. Upon 'eachr leg 12 ofthe. U-bolt 10, 11, 12, there is disposed outwardly from thel L-bracket14, 16, a helical spring 20 which may be assembled into compressibleposition by nut 21 held in locked position by lock nut 22. .These nuts21, 22, may be so adjusted on the threaded portionsv 13 of the legs12as; to bring the square cross-section helical compression spring 20 toslightly compressed position thereby firmly holding rocker bearing pin18 in the bearing 23. I

This bearing 23 is a part of a sheet metal saddle. This bearing 23 isshown `as having lon one side thereof lan upstanding `rib orcorru'gation 24 as terminating ina downwardly extending free end 25.'The opposite side of this bearing 23 has a second corrugaton or ribportion 26 terminating in main flat portion 27 providing the mainsupport oi' bearing for this saddle, which Hat portion 27 is in theplane of the free end of the downwardly bent portion 25. This main fiatportion 27 of the saddlek is shown as having oiiiset portion 28 remotefrom the bearing 23 to have downwardly struck portion 29 carrying hookportion 30, which extends under the respective leaf springs 4 and 8 andthereby not only maintains the spaced relation for the bearing 23 as tothe link 3 or 7 but also holds the saddle against upward movement as tothe spring.- y

In practice, it is found acceptable, to design the device somewhatlarger for the rear axle than for the forward axle. In an automobileequipped with the devices of this disclosure there is not onlyassistance givento the steering in that there is reduced vibration ofthe front axle as to the vehicle, but the car is at all times maintainedWith its Wheels on the road regardless ot the .roughness `ot-the roadsor the speed of the obtained to the comfort ot the passengersin the car.This means there is a smoothness vand steadiness ont .riding ot' :thecar Which meansthere is agreat reduction in the Wear on the Car as wellason the tires. rl'there is 'avoidance o'fany side sway 1n the travelyof the vehicle even ot the Fordtype.
